TUBING SUPPORT.

Application filed 'June 24, 1926. Serial No. 118,329.

My invention relates to a'tubing ring and stufling box therefor and support for tubing; and the object is to provide a practical sup port for the tubing and also to provide a stuffing box to retain venting waste of oil and gas. One of the ad vantages of this invention is that the slips heretofore inuse cannot be used to form pack-.

mg glands and my invention overcomes this difliculty by making combined slips and pack,- ing gland so that the slips may be used to form a packing gland and another object is to provide means for preventing the slips from falling from the well tubing. In other forms f li the slips will fall off of the tubing when the tubing is raised. I have provided means for holding: the slips on the tubing. Other objects andadvantages will be fully explained in the following description and pointed out in the claims.

Reference is had to the accompanying drawings which form a part of this application.

Fig. 1 is a plan view, showing the improved slips applied to atubing.

Fig. 2 is a side elevation one of the slips omitted.

Fig. 3 is a perspective view of one of the members of a spreading ring.

Fig. 4 is a bottom plan view of the packing gland and the improved slip for use on tubing.

' The drawings show the various parts of the invention. Instead of the tubing ring heretofore in use, I have provideda combined tubing ring 1 and stuifing box 2 to be used with theimproved method of spreading the packing on the underside of the packing. The tubing ring 1 has the .usual annular interior shoulder 3 to support the spreading of a tubing with 7 ring 4 which is V-shaped on the upper side.

A packing. ring 5 of rubber or other packing means, such as asbestos, hemp, or rags is placed on the spreading. ring 4. When the slips come down on the packing 5, it Wlll be 5 spread on the underside both radially inthe gas or oil for pre fluid from below the packing,

the invention will be more particularly' ward against the tubing 6 and radially outward against the stufiing box 2. The advantage of spreading on the underside of the packing is that the more pressure that comes on the packing from the force of the gas or the tighter will be the packing against the stufiing box and against the tubing.

have provided a departure in the slips used. The slips are tapered, as slips usually are, but the taper is for an entirely different purpose. The stufiing box 2 is larger in diameter at the upper end so that the packing ring 5, maybe easily inserted. The slips are let down on the packing 5 and forced downwardly. The packing 5 will be reduced inwardly' by the compression by the tapering Wall of the stufling box and thus make the packing tighter as it is forced downwardly by the slips. There are several slips .and the number of slips may be varied- I show two slips 7 of the common type except that they have an annular exterior groove 'in the periphery thereof for a U-bolt-8 and they ,have an annular exterior rib 9 for resting on the top edge of the stufling box 2 and supporting the immense weight on the stuffing box 2-instead of supporting the entire weight on the packing 5. The other member 10 of the slips has provision for carrying a yoke 11. The yoke 11 has laterally projecting ears 12 and the object of the ears 12 is to make provision for using the U-bolt 8 to clamp the slips rigidly together. The "U-bolt 8 .occupies the groove in the periphery of the slip members 7 and the ends of the U-bolt project through the ears 12 and nuts 14. The slips 7, 7, and 10 have teeth 15 similar to other slips. The bottoms of the slips take the place of a compression ring for compressing the packing 5. The U-bolts 8 will make the slips engage the tubing rigidly so that knocking or pounding on the slips to make them engage the tubing is dispensed with. The slips are not tightened or wedged in stufling boxes as in spiders or tubing supports of a different type. In my form of slips, the slips cannot fall off when the tubing is lifted or forced upwardly by gas pressure but will re main on the pipe or tubing and go back in place, and not fall'ofl as in other forms of .sl-ips. The slips herein set forth may be used a V-shaped upper side, a packing ring mountf ed on said spreader, sllps mounted on a well 1 tubing and provided with a peripheral rib adapted to rest on the up er edge of said stuffing box and said slips eing adapted to engage said packing ring to force the same down on said spreader for sealing purposes,

and means for binding said slips on said tub 2; A tubing support comprising a combined tubing ring and stufling box, slips mounted on a well tubing and provided with means for supporting the slips on said stuffing box, one of said slips having an integral yoke, and the other slips having a peripheral groove, and a U-bolt mounted in said groove and projected through said yoke and nuts for engaging the ends of the U-bolt for binding said slips on said tubing.

3. A tubing support comprising a combined tubing ring and stufiing box, sealing means mounted in said stufiing box, slips mounted on said stufiing box and projected down into said stuffing box for actuating said sealing means, one ofsaid slips having laterally projecting perforated lugs and the other slips having a peripheral groove, a U-bolt mounted in said groove and projected through said lugs, and nuts engaging the ends of said U-bolt for binding said slips on a well tubing;

4. In a tubing support; slips for support- .ing a tube comprising slips having the usual interior teeth for engaging a tube, one slip having a groove about its periphery and the other slip having an exterior yoke, mounted in said groove and havin its arms projecting through said yoke, and nuts for clamping said slips on said tubing.

5. Slips for supporting a well tube comprising slips having the usual interior teeth for engaging the tube, one slip having a groove in its periphery and theother slip hav ing an integral yoke and ears p1 :ojecting from said yoke, a U-bolt mounted in said groove and having arms projecting through said ears, and nuts for engaging said arms to clamp said slips on the tube.

6. Slips for supporting a well tube comprising slips having the usual interior teeth for engaging the tube, one slip having a groove in its periphery and the other slip having an integral yoke and ears projecting from said yoke, a U-bolt mounted in said groove and having threaded arms projecting through said ears, nuts engaging said arms for clamping said slips on the well tube, and exterior ribs integral with said slips for supporting the same.

In testimony whereof, I set my hand, this 29th day of May, 1926.
